Description

Technical Field

[0001] The utility model relates to the technical field of compression resistance detection of building materials, in particular to a compression resistance detection device for building materials. Background Art

[0002] The materials that need to be tested for compression resistance in building materials are usually solidified concrete specimens or lightweight refractory bricks used for wall construction. The best way to test the quality of lightweight refractory bricks is to apply a certain pressure to the lightweight refractory bricks to observe whether there are indentations on the surface of the lightweight refractory bricks. Usually, this kind of compression resistance test is carried out on a detection device that can apply pressure.

[0003] In the prior art: a Chinese patent document with publication number: CN220473166U and publication date of February 9, 2024 is proposed. The technical solution disclosed in the patent document is as follows: it includes a bottom box and a slag collecting box, a transparent baffle is fixedly connected to the top of the front of the bottom box, a belt is installed in the middle of the top of the bottom box, a flat plate is provided on the inner side of the belt, a vertical plate is fixedly connected to one side of the top of the bottom box, a hydraulic cylinder is installed on the top of the vertical plate, and a pressure plate is connected to the output end of the hydraulic cylinder, and both sides of the bottom of the pressure plate are A soft cloth belt is fixedly connected. The utility model provides a compression testing device for building materials. Through the soft cloth belt, counterweight strip, transparent baffle, first clamp, limit plate, belt, flat plate, slag collecting box and drawer box, the probability of slag splashing during testing is reduced, and the material slag splashing to the test personnel is blocked, thereby reducing the probability of the test personnel being injured by the splashing objects, eliminating the step of manually cleaning the slag on the test table, and the lightweight brick debris remaining in the test area of ​​the table top is wiped and cleaned in time, thereby reducing the interference with subsequent lightweight brick testing.

However, the refractory bricks will splash around when splashing, so the protection effect of using a transparent baffle is not good. The refractory bricks still need to be cleaned up when they fall around, which is time-consuming and laborious. Therefore, a building material compression test device is proposed.

[0023] See also Figure 1-6The utility model provides a technical solution: it includes a workbench 1, the workbench 1 is a table structure, and then a rectangular slot 2 is opened in the middle of the rectangular plate on the top of the workbench 1, a reinforcing rib 3 is welded on the inner wall of the slot 2, and then a placement plate 4 is welded on the surface of the reinforcing rib 3, the placement plate 4 is a rectangular structure, and the placement plate 4 is in the middle of the slot 2, and then a first limiting plate 5 is fixed by screws on the top of the workbench 1 and on one side of the slot 2, the first limiting plate 5 is a triangular structure, and a ridge groove is opened on the side of the first limiting plate 5, and the first limiting plate 5 is a triangular structure. The electric push rod 6 is fixed with screws on the top of the platform 1 and on the other side of the slot 2. The output end of the electric push rod 6 is connected to the second limit plate 7 by a pin shaft and other connecting parts. The second limit plate 7 is a rectangular plate structure. Then, a ridge groove is also opened on the side of the second limit plate 7 opposite to the first limit plate 5. Then, refractory bricks and other building materials are placed on the placement plate 4, and then one side is made to fit with one side of the first limit plate 5. Then, the electric push rod 6 is started to drive the second limit plate 7 to move toward the refractory bricks and other building materials, and the refractory bricks and other building materials are clamped by the first limit plate 5 and the second limit plate 7.

[0024] A fixing plate 8 is fixed on the top of the workbench 1 by screws, and the shape of the fixing plate 8 is an L-shaped structure. At the same time, one of the surfaces of the fixing plate 8 is parallel to the placement plate 4 and is located directly above the placement plate 4. Then, a presser 9 is fixed by screws at the surface of the fixing plate 8 directly above the placement plate 4. Then, a circular hole is opened on the surface of the fixing plate 8, and a pressure rod 10 is fixed at the output end of the presser 9 by screws and other structures. The presser 9 is a hydraulic cylinder structure that can be lifted and lowered. A pressure plate 11 is fixed by screws at the end of the pressure rod 10 away from the pressure device 9. The shape of the pressure plate 11 is rectangular, and the pressure plate 11 is also located directly above the placement plate 4. After the presser 9 is turned on, the pressure rod 10 can be driven to rise and fall, and then the pressure rod 10 can be used to drive the presser 9 to rise and fall. , the pressure device 9 is used to realize the compression test of refractory bricks and other building materials, the fixing ring 12 is connected to the surface of the pressure rod 10 by means of screws and other components, the fixing ring 12 is a circular ring structure, and then a circle of springs 13 are glued to the top of the fixing ring 12, the number of springs 13 is several, and then a barrier cover 14 is glued to the end of the spring 13 away from the fixing ring 12, a circular hole is opened on the top surface of the barrier cover 14 and at the position of the pressure rod 10, and then the pressure rod 10 is set to pass through the circular hole. Under normal conditions, the pressure rod 10 drives the barrier cover 14 to move up and down, and a card slot 15 is opened at the bottom position of the side of the barrier cover 14 corresponding to the moving track of the electric push rod 6. The setting of the card slot 15 can prevent the barrier cover 14 from affecting the start of the electric push rod 6 after it falls;

[0025] The pressure device 9 drives the pressure rod 10 to move downward, and the downward movement of the pressure rod 10 will drive the pressure plate 11 and the barrier cover 14 to move downward synchronously. Because the bottom of the barrier cover 14 is lower than the pressure plate 11, the bottom of the barrier cover 14 first contacts the workbench 1. Then, after the bottom of the barrier cover 14 contacts the workbench 1, when the pressure rod 10 continues to move downward, the spring 13 will be stretched, so that the pressure rod 10 will not affect the barrier cover 14 when moving downward. Then, after the pressure plate 11 contacts with refractory bricks and other building materials, a pressure test can be performed. In the case of continuous pressure test, refractory bricks and other building materials may be broken. When broken, the refractory bricks will splash, and the splashed refractory brick materials will be blocked by the barrier cover 14. The splashed materials may accidentally injure the staff or scatter on the ground to cause cleaning troubles.

[0026] Then, a clamping plate 16 is fixed with screws at the bottom of the rectangular plate of the workbench 1 and at the position of the slot 2. There are two clamping plates 16, and the two clamping plates 16 are symmetrically fixed on both sides of the slot 2. Then, a placement box 17 is inserted between the two clamping plates 16. The two top edges of the placement box 17 are inserted into the slot holes of the clamping plate 16, thereby fixing the placement box 17. When the refractory bricks are broken and fractured during the compression test, the splashing materials are blocked by the barrier cover 14 and then fall into the placement box 17 through the slot 2. Then, the electric push rod 6 is turned on to drive the second limit plate 7 to move. The second limit plate 7 can be used to push the broken materials accumulated on the surface of the placement plate 4, and then fall into the placement box 17 through the slot 2, thereby realizing automatic recovery and cleaning of the materials.

[0027] Working principle: When in use, the utility model first places the workbench 1 at the working position, and then places refractory bricks and other building materials on the surface of the placement plate 4, so that one side thereof is in contact with the side of the first limiting plate 5, and then the electric push rod 6 is turned on to drive the second limiting plate 7 to move toward the building material, in contact with the other side of the building material, and clamp the building material, and then the pressure device 9 on the top of the fixed plate 8 is turned on. Under the action of the pressure device 9, the pressure rod 10 moves downward, and the pressure rod 10 moves downward with the pressure plate 11 and the barrier cover 14. Because the bottom of the barrier cover 14 is lower than the pressure plate 11, the barrier cover 14 first contacts with the surface of the workbench 1, and during the continuous downward movement of the pressure rod 10, the fixing ring 12 and the barrier cover The spring 13 between 14 is stretched, so that the pressure rod 10 can move downward without affecting the barrier cover 14. When the pressure plate 11 contacts the building materials such as refractory bricks, a pressure test is carried out. When the building materials are broken during the pressure test, the barrier cover 14 can prevent the material from splashing. A part of the intercepted material enters the placement box 17 through the slot 2, and the other part accumulates on the surface of the placement plate 4. At this time, the electric push rod 6 is started to drive the second limit plate 7 to move toward the first limit plate 5, and the material accumulated on the surface of the placement plate 4 is pushed into the placement box 17 through the slot 2, and then the placement box 17 is pulled out from the inside of the card plate 16. After the material is poured out, the placement box 17 is inserted into the inside of the card plate 16.
